五官 (wǔ guān): five sense organs of TCM (nose, eyes, lips, tongue, ears 鼻目口舌耳); facial features

Traditional Chinese medicine believes that the five sense organs are closely related to the five internal organs; by observing the condition of the eyes, ears, nose, lips, and tongue, one can understand the health status inside the body.

The doctor carefully examined the patient's five sense organs and found that his tongue was reddish and had a yellow coating, so he judged that there was heat in his body and that he needed to clear the heat and reduce internal fire.

In TCM diagnosis, changes in the five sense organs can often reflect problems of the internal organs; for example, tinnitus in the ears may suggest kidney deficiency, and dry eyes may be related to insufficient liver blood.

The veteran TCM doctor told him that the five sense organs are the windows for observing the internal organs, and that he should usually take care to protect his eyes, ears, nose, lips, and tongue to avoid dysfunction caused by overuse.
